Cheap/Easy Tachometer and Battery Status meters, plus many other functions, for your Hybrid Maverick

For about $25, less if you have Amazon prime, you can have the Tach, Battery Status and a whole lot more. Best part is there is no wiring involved.

I'm an absolute noob to OBD2 so I'm comfortable that most anyone can use this. It can take you a couple of minutes to connect each time you travel, but if you are like me and are just curious about the battery usage or miss the tach, this is an easy solution using an Android App and a Bluetooth OBD2 reader.




The App is Car Scanner ELM OBD2. There are a few functions not included in the free version, but the paid version is only $5. You can find it at:
https://play.google.com/store/apps/details?id=com.ovz.carscanner

The OBD2 reader I use is Veepeak Mini Bluetooth OBD II Scanner for Android ONLY. It can be found at:
https://www.amazon.com/Veepeak-Blue...pd_bap_d_grid_rp_0_1_ec_pr_pd_hp_d_atf_rp_4_t

The app has a built in demo version so you can download it and play around with it without the reader. The first option once loaded is a configurable dashboard option which is what I used in the pictures above. There are several different chart types available to choose from. All in all it is a cheap easy way to scratch an inch.

Again, I am not an expert, but it is my understanding that over an extended amount of time the scanner can drain your battery so be safe and unplug it when not in use.

One more note. According to the scale provided in the chart, the battery percentage tops out at 80%. So far 67% if the highest I have seen it go.

I use that as well.

I have a little voltmeter I plug into the cigarette lighter. Works well and gives some good feedback.

I'm curious if anyone has found a transmission temp sensor readout? I couldn't find it using that app.

I cannot either. I do not believe there is a sensor.

I have a 4 port USB extender which plugs into the cigarette lighter that also has a voltage readout. Very handy!

OK... Lots of guessing .... The stock battery is a 36+ month battery. Some of the first ones had the date manufactured printed on the bottom of the top label. The 80% figure on a different thread for different Ford pickup was stated by an engineer (Ford?, who knows) to be set to prevent max amp input heating being fed to battery particularly in hot or very cold climates. The heat is super detrimental to battery life. Also stated was it's very important when changing to a new battery to preferably update the date installed manually (the truck battery learn procedure may take several attempts so best to have dealer do it if you don't have forscan or?). The BMS uses the target charge (80%?) and adjust charging parameters number of days installed being one. It was stated by someone if not the "engineer" that the BMS was an inline battery analyser. It was implied that due to aging along with the fact that the BMS measures the current available for the battery and the amount of current that was not accepted. This implies that the battery would be considered fully charged when no further current would be accepted. It was also stated that the battery should be charged with a multi stage (5 to 9) maintainer of at least (if I remember correctly) 4 amps ( I remember my noco 5 was barely big enough). In short I believe that your 67% might be the 80% adjusted by time and usage. There have been others claiming theirs settles to 65% but none have reported less than I am aware of. If the installed date is not updated the BMS may assume the new battery installed voltage is its max or worse assume that your old battery is still the one that is being charged. I cannot for a few days but will see if I can find the thread.

According to John Kelly at Weber State there are three temp sensors one fluid and one on each motors field coils. Logically they are still there as when in low downhill it may shut down with pop up screen "due to temperature". Could be HVB temp sensor also.

Torque is another great app. It does all of the ODBII functions and code clearing but it also has race info and you can configure Tach, fuel, speedometer, etc. screens. It's a free app and I've helped dozens of people with vehicle issues with it.

When setting up my gauges with CarScanner, it list a bunch of different options, it does show transmission temp but no data ever appears there for me. Perhaps there may be a custom PID but I don’t know what it could be. This Hybrid machine is all magic to an old guy (me) & from what I for now understand this “transmission“ is planetary gears with no clutches, so temp (as long as it’s properly filled) should not be an issue.

There are two three phase electric motors brushless with magnets. The field coils have square wires with 90° bends so they fit close together (saves copper and allows motors to be smaller) and are enclosed in a polymer. The fluid contains additives to help keep the coatings in good shape. The fluid is pumped over the field coils to keep them from melting. You are correct in that the oil must be properly filled.

very cool, i think this is something a lot of folks wish they had.

I use Forscan Lite on my android phone and it will show any PID data you can find, including transmission temp. Plus no annoying ads popping up.

You can get the Torque app to show up on Android Auto (truck screen). Can show lots of different gauges, also.

OBD Fusion on IOS supports carplay.
